Specs & Features

• Stop the Snap: Specifically designed to reinforce the weak factory sway bar mounting tabs, preventing them from cracking, bending, or shearing off under heavy load.
• Triangulated Strength: Mounts between the sway bar bracket and the rear lower control arm bolt, creating a rigid triangle of support that distributes stress evenly into the chassis.
• Stealth Finish: Coated in a durable Dark Grey Powder Coat that looks like high-end OEM equipment and blends seamlessly into the underside of the car.
• Complete Kit: Sold as a pair (Left & Right) and includes all necessary Installation Hardware, so you aren't stuck running to the hardware store mid-install.
• Great Insurance: The most cost-effective way to protect your subframe from permanent damage caused by stiff aftermarket sway bars.

Product Description

The factory sway bar mounts are just thin tabs of sheet metal. They were designed for a skinny, flexible stock bar. When you upgrade to a thick 22mm or 24mm solid sway bar, you are introducing massive amounts of leverage and torque that those little tabs were never meant to handle. Without reinforcement, it is not a matter of if they will crack, but when. The COBB Tuning Sway Bar Mount Reinforcement Brace is the structural fix for this weak link.

This isn't just a shiny bracket; it’s a structural support beam. By connecting the lower sway bar tab directly to the heavy-duty rear lower control arm bolt, COBB effectively "triangulates" the mounting point. This means when you dive into a corner and the sway bar loads up, that force is transferred into the sturdy subframe rather than just twisting the flimsy sheet metal tab.

If you are installing a rear sway bar, this should be mandatory. It is the definition of "do it while you're in there." Installing these braces takes minutes, but repairing a torn subframe mount takes hours of welding and fabrication. Don't risk your chassis for the sake of saving a few bucks.

COBB Tuning knows that performance isn't just about going fast; it's about durability. This reinforcement kit is peace of mind in a box. It allows you to run the stiffest sway bar settings and sticky tires without worrying about structural failure. "You are only as strong as your weakest link"—don't let that link be your mounting tabs.
